Functional Description
IS200TRLYH1CDB is a Relay Output with contact sensing terminal board developed by GE. It is a part of the Mark VI control system. The terminal board is designed to accommodate 12 plug-in magnetic relays, providing robust and reliable control. To convert the solenoid outputs to dry contact type, six jumpers that were initially associated with fuse monitoring need to be removed. This modification ensures that the solenoid outputs function correctly as dry contacts.
Features
- Relay Circuits: The first six relay circuits are Form-C contact outputs. These outputs are specifically designed to drive external solenoids, making the board suitable for controlling a wide range of electromechanical devices.
- Power Source: The board supports a standard 125 V DC or 115 V AC power source. This versatility allows for compatibility with common power supplies used in industrial environments.
- Fuses and On-Board Suppression: The terminal board includes fuses and on-board suppression to protect the field solenoid power circuits. These features enhance the safety and reliability of the system by preventing electrical faults and minimizing the risk of damage to connected devices.
- Plug-In Magnetic Relays: The use of plug-in magnetic relays makes it easy to replace or upgrade relays without extensive downtime, ensuring quick maintenance and high availability.
- Form-C Contact Outputs: The Form-C contact outputs provide reliable switching for driving external solenoids, making these terminal boards versatile and suitable for various control applications.
- Protection Features: Built-in fuses and on-board suppression enhance the safety and reliability of the system by protecting against electrical faults and reducing the risk of damage to connected devices.
- Versatile Power Sources: The availability of different power source options (125 V DC, 115 V AC, and 24 V DC) ensures compatibility with a wide range of industrial power standards and requirements.
Control Compatibility
- The board is designed for seamless integration with and control by the VCCC or VCRC boards. These boards ensure the terminal boards function effectively within both simplex and Triple Modular Redundant (TMR) applications, providing flexibility and reliability for various operational needs.
- The VCCC board houses the control cards responsible for managing the operations. It facilitates accurate communication and control signals, ensuring efficient operation of the terminal boards. On the other hand, the VCRC (VME Control Redundancy Carrier) board provides redundancy in control operations, enhancing system reliability and fault tolerance. It ensures continuous operation even if one control path fails, making it suitable for critical applications where high uptime is essential.
- The terminal boards are designed to support both simplex and TMR configurations, allowing for flexible deployment based on specific reliability requirements and operational contexts. In simplex configurations, the terminal boards are controlled by a single VCCC or VCRC board. Connector JA1 is used to connect the terminal board to the VME rack, where the I/O boards are mounted. This setup is ideal for applications where single-path control suffices, providing a straightforward and cost-effective solution. In TMR configurations, the terminal boards are controlled by three VCCC or VCRC boards, providing triple redundancy. Connectors JR1, JS1, and JT1 are used to connect the terminal boards to the VME rack, ensuring multiple redundant paths for control signals. This setup is crucial for applications requiring high reliability and fault tolerance, as it allows the system to maintain operation even if one control path fails.
- The connection between the terminal boards and the VME rack is established through cables with molded plugs. These plugs are designed to ensure secure and reliable connections, facilitating stable communication and controlling signal transmission. In simplex systems, connector JA1 links the terminal board to the VME rack, enabling efficient and straightforward installation and operation. In TMR systems, connectors JR1, JS1, and JT1 provide multiple redundant paths for control signals. This configuration enhances the system's fault tolerance, ensuring continuous operation by maintaining control even if one path fails.
Installation Procedure
- Wiring Relay Outputs: Connect the wires for the 12 relay outputs to the two I/O terminal blocks on the terminal board. Each terminal block is secured with two screws and contains 24 terminals that can accommodate wires up to 12 AWG in size. A shield terminal strip is attached to the chassis ground and is located immediately to the left of each terminal block. This strip helps ensure proper grounding and shielding, reducing electrical noise and interference.
- Connecting Solenoid Power for Outputs 1-6: The solenoid power for outputs 1-6 should be connected to connector JF1 as standard practice. If you need to daisy-chain power to other terminal boards, you can use connector JF2 for this purpose. This configuration allows for efficient power distribution across multiple boards. Alternatively, if connectors JF1 and JF2 are not used, you can wire the power directly to terminal block TB3. This direct wiring method provides flexibility in power connection setups based on specific installation requirements.
- Connecting Special Solenoid Power (Output 12): The power for the special solenoid, designated as Output 12, should be connected to connector JG1. This dedicated connection ensures that the special solenoid receives the appropriate power supply independently from the other outputs.

Frequently Asked Questions
What is IS200TRLYH1CDB?
It is a Relay Output with contact sensing terminal board developed by GE under the Mark VI series.
How does the ID device improve system reliability?
The ID device improves system reliability by allowing the I/O processor to verify that the correct terminal board is installed. When the I/O processor reads the ID chip, it checks for compatibility between the terminal board and the system configuration. If a mismatch is detected, it indicates a hardware incompatibility fault, preventing potential operational issues caused by incorrect or incompatible hardware.
What happens if there is a mismatch in the ID device information?
If the I/O processor reads the ID chip and encounters a mismatch in the stored information (such as an incorrect board type, serial number, revision number, or connector location), it generates a hardware incompatibility fault. This fault alerts the system operators to the issue, preventing the system from operating with incompatible hardware and ensuring that only the correct components are used.
Why is it important to avoid hardware incompatibility faults?
Avoiding hardware incompatibility faults is crucial for maintaining the integrity and reliability of the control system. Incompatible hardware can lead to operational failures, increased maintenance requirements, and potential safety hazards. By using ID devices to verify compatibility, the system ensures that all components are correctly matched and function as intended.
